Railroad-station indicator



CHAS. J. SMITH, OF NORTH PRAIRIE, WISCONSIN.

RAILROAD-STATION INDICATOR.

Specification of Letters Patent No. 19,880, dated April 6, 18158.

To all whom it may concern:

Be it known that I, CHARLES J. SMrri-r, of North Prairie, in t-he county of Vaukesha, State of lVisconsin, have invented a new and Improved Railroad-Station Indicator for Indicating and Announcing to Passengers the Names of Stations on Railroads; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters f reference marked thereon, making a part of this speciiication.

Figure one (l) is a front view of the indicator with the name of the station appearing through the aperture in the case. F two (2) is a perspective view showingv the cylinders or rollers, and the mode of attaching them. Fig. three (3) is also a perspective view showing the method of moving the cylinders or rollers. Fig. four (4) is an elevation, showing a combination of levers and the manner in which they operate.

The. nature of my invention consists in placing a scroll of paper, cloth or other fabric suitable for the purpose upon the rollers A and B (Fig. 3), the rollers being attached together by gearing as seen in A, B and C (Fig. 2). The center wheel B is the driv` ing wheel, and when turned moves the names upon the scroll up or down, as desired. Attached to the other end ofthe shaft D (Fig. 3) is a wheel E having pegs or teeth upon the side, which is turned either way by means of the perpendicular bar F, having pawls G, G, upon it, the bar F being thrown up or down by the .lever K (Fig. 2).

Attached to the end of the upright lever A (Fig. 4) is a cord or wire, which being pulled by the operator forces the horizontal angles with, the lever A, the horizontal lever B having slots or openings to admit the pins and having the fulcrum at one end forced down by the pin C to the left of the center and up by the one on the right side, the horizontal 'lever being thrown from one pin to the other by the crank and connecting rod E (Fig. 4). Upon the end of the crank shaft F and project-ing through the case is a small index finger' which being turned half around moves the lever from one pin to the other, and effects a change of motion. Attached to the machine is a bell, which is struck by means of a pin projecting from the upright lever A coming in contact with a lever connected with the stem of the bell hammer.

I claim neitherthe cylinders nor the scroll, but

The shifting lever or bar B and the mode of adjusting it by means of the index finger at the end of the crank'sh aft F, in such manner as to cause the rollers or cylinders to revolve in opposite directions by means of the same application of power, in combination with the pin or stops upon the lever A,

and the slots or openings in the aforesaid shifting lever or bar B, arranged specifically as shown and described for the purposes set fort-h.

Dated December 30th, 1857.
